JAMES H. BELL, OF ST. LOUIS, MISSOURI..

FIRE-EXTINGUISHER.

No.e64,149.

To all whom 'it may concern:

Be it known that I, JAMES H. BELL, a citizen of the United States,residing at St. Louis, in the county of St. Louis City and State ofMissouri, have invented certain new and useful Improvements inFire-Extinguishers, of which the following is a specification.

This invention is a iire extinguisher for oil or gas wells and has forits object to provide a simple and elicient device of this kind, andalso one which can be easily operated.

The device comprises a tapering plug which is dropped into the well-tubeand smothers the fire. Means are provided for the escape of gas from theplug.

In the accompanying drawing, Figure l is an elevation of the inventionshowing the application thereof. Fi 2 is a longitudinal section. Fig. 3is a top plan view. Fig. 4 is a cross-section on the line 4-4 of Fig.'2.

Referring specifically to the drawing, 6 denotes an elongated conicalplug which is hollow, its bore 7 forming a water-chamber. The plug has aremovable tip 8 which is secured by screwing it thereon. Ondiametrically opposite sides ofthe bore 7 the block has longitudinalpassages 9 which extend from the top of the plug and open into the sidesthereof about midway between its ends. In the top of the plug are iittedstop-cocks l0 for the bore 7 and stop-cocks ll for the passages 9. Tothe top of the plug is also secured an eye 12 for attachment of ahoisting device.

In use, the chamber 7 is filled with water and the plug is inserted intothe tube of the burning well, the

cocks ll being left open to permit the escape of gas through thepassages 9. The cock l0 is also left open in order that any steam which:may form in the waterchamber 7 by reason of the heat from the fire mayescape. The water prevents the plug from getting hot enough to set theoil or gas on fire. If steam is made, the water-chamber will be relled.As the needle descends in the Well-.tube the iire is gradually smotheredafter which the oil will commence to flow from the cocks 1l whereuponthey are shut off. If the diameter of the well-tube is such that theplug will not t tightly, the top of the tube can be packed with a ringof clay or other non-combustible material.

I claim:

1. A re extinguisher for gas and oil Wells comprising a plug adapted tohe inserted into the Well-tube, and having gas outlets.

2. A tire extinguisher for gas and oil Wells comprising a plug adaptedto be inserted into the well-tube, and having gas outlets and a chamberto receive a cooling medium.

3. A fire extinguisher for gas and oil wells comprising a plug adaptedto he inserted into a well-tube, and having gas outlets, and valvescontrolling said outlets.

4. A fire extinguisher for gas and oil wells comprising a conical plugadapted to be inserted into the well-tube, and having' longitudinalpassages extending from the top and opening into the sides of the plug.In testimony whereof I atlix my signature, in presence of two witnesses.

JAMES H. BELL.
